Creating an RPM of some binary

We've covered this topic before in this story about creating an RPM from a shell script, but this information might help you better understand how to create an RPM.

So; you've found a piece of software that has no RPM? (Or; your manager tells you to install a piece of software that the development department created.)

Normally you'd use ./configure ; make ; make install, here is how to put that all in an RPM.

Prepare your rpm building environment: (DO THIS AS A USER!)

$ sudo yum install rpm-build
$ mkdir -p RPMBUILD/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
$ echo "%_topdir /home/username/RPMBUILD" >> .rpmmacros

Now copy the software into that newly create structure.

$ cp software.tar.gz RPMBUILD/SOURCES/

And now create a "spec file" for the software. This basically explains rpmbuild how to make the software and what to put in the RPM. This is the most "tweakable" step and might require quite some time to get right. Put this into /home/username/RPMBUILD/SPECS/software.spec:

Name: software
Version: 0.23
Release: 1
Summary: Custom software to run enterprise servers.

Group: Applications/Internet
License: GPLv2
URL: http://meinit.nl/
Source0: %{name}-%{version}.tar.gz
BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root

%description
This software runs all enterprise software as a daemon. It's been developed by Me in IT consultancy.

%prep
%setup -q

%build
make

%install
mkdir -p $RPM_BUILD_ROOT/usr/local/bin
install software $RPM_BUILD_ROOT/usr/local/bin/software

%files
%defattr(-,root,root)
%doc README
/usr/local/bin/software

%clean
rm -rf $RPM_BUILD_ROOT

%changelog
* Tue Jun 15 2010 Robert de Bock <[email protected]> - 0.23-1
- Initial build

Good to know; the %install refers to the temporary environment that rpm will create when building this RPM. The %files section refers to what will end up in the RPM. They should correspond; you can't %install a whole bunch of files and only include a few in the $files part. (rpmbuild will display the missing files.

The group can be any line out of /usr/share/doc/rpm-*/GROUPS

So; you are prepared, run this command to so if you got everything correct:

$ rpmbuild -ba software.spec

When it finally builds, you'll find the rpm in /home/username/RPMBUILD/RPMS/$arch/software-0.23-1.$arch.rpm
